Abstract
This invention relates to a pixel circuit comprising a photo-sensor stage () comprising a photodiode () delivering a photoreceptor current (I), a comparison stage () configured for detecting a change in a signal voltage (V) derived from said photoreceptor current, a sample-and-hold circuit () connected to the converting stage () and to the comparison stage (), said comparison stage () configured to output an input signal for the sample-and-hold circuit (), and for emitting a sampling signal to a control terminal of the sample-and-hold circuit () when a change is detected in the signal voltage (V).
